"COUPLING.

To ZM/)hom 15mm/x concern Be 1t `known that I, OBRA QE. :.BYnoNfa .citizen ,of fthev United `States, residing l.at

followinglto be a ffull, clear, and exact-description of the same, such as willenable others skilled in the artztowhich it pertains to make and -use the-same, `reference `being had to theaccompanying dnawings, which form apart of. this. specification.

This invention relates to couplers, =espe cially couplers between two road vehicles.

It comprises avery simple device in which the two coupling members are brought together andconnected and lcanbelocked in this position.

Figure l is a plan view of the female member, partly in section.

Fig. 2 is a vertical section of the female member.

Fig. 3 is a plan view of the male member.

Fig. 4 is a vertical section of the male member.

Fig. 5 is a vertical section of the two members interlocked.

The female member comprises a bell-like head having at its sides inside, a pair of shoulders a, a, beveled on the forward side, and each provided with a recess or cradle back of the slopingvforward side. The top of the bell is cut away at the rim while'at the center of this cut-away portion is a reentrant recess c terminating in a part-circular countersink d.

The male member comprises a perforated and forked end c through the perforations in whose arms passes the pin f projecting beyond the arms at each side. Between the arms of the forled end is a sleeve jt pivoted upon the pin f. The sleeve is provided with a laterally projecting segmental head or cam g. Radially into this threads a bolt z' encircled by a coil spring j that abuts against the head of the bolt at one end and against the sliding sleeve k at the other end.

It is evident that when the two coupling members are alined, or substantially alined, the ends of the cross pin f will strike the beveled face of the shoulders a when the two coupling heads are moved toward each other and these pins f will drop into the 'Specification of Letters'latent.

- cradles -b fwhich will connect l;the .1two coupling members for :the .purpose of gpushing or pulling, but the members are not thereby securely interlocked. This, however, is -easily `effected by reason of throwingpver .tovertical -position the'loclring device. This can easily,` be, done, the sleeve le rising slightly when stri-kingthe couplingheath-allowing it `fto .then 1 drop vinto ithe countersink CZ .where Vithespringyltends to .keeptthe lock linplaee. ,It will beevident that 1the oamfg bearing against the inside of the ,female coupling :member fabsolutely prevents the g pin .ends bounding out of the .cradles z as 'long as 1 the locking. devices are i in vertical position.

What I claim is:

:1. fIn coupler, the ,combination of .-a fe- Irnalecoupling head or socket provided on the inside with a beveled shoulder and a cradle to the rear thereof, a male coupling member provided with a projecting pin adapted to strike said shoulder on the beveled side and ride thereover and drop into the cradle, and means on the male member for preventing relative up and down movement between the male and female members after the pin has dropped behind the shoulder. Y

2. In a coupler, the combination of a female member having at one side a shoulder beveled in front and providing a cradle at the rear, a male member provided with a projecting pin adapted to ride over the bevel on the shoulder and drop into the cradle, andv a cam on the male member which can be turned up to lill the space between the male and female members, thereby preventing the pin from jumping out of the cradle.

3. In a coupler, the combination of a female member in the form of a bell-like head, a shoulder at the side of said head beveled in front and provided with a cradle to the rear, the said head being provided with a slot about 90 degrees removed from the shoulder, a male coupling member provided with a projecting pin adapted to ride over the bevel of said shoulder and drop into the cradle, a cam adapted to be turned up and having an attachment engaging in said slot, thereby preventing the pin from jumping out of the cradle, and means for retaining the said cam in said turned up position.v

4. In a coupler, the combination of a female member in the form of a bell-shaped head, a shoulder beveled at its forward por? tion and having acradle to the rear, the said head being provided with a slot substantially 9() degrees removed from the shoulder terminating in a countersink, a male member provided with a projecting pin, a cam swiveled lon the male member and provided with a bolt, a locking sleeve reciprocating on the bolt, said bolt being arranged to pass through the slot in the female coupling head and the cani, bolt and sleeve turned up into vertical position to bring the locking sleeve into the countersink, locking the pin in the cradle.

5. In a coupling head, the combination of r a female member in the form of a bell having on the inside at each side a shoulder beveled in front and having a cradle at the rear, a male member having a forked end with a pin passing through and projecting at each side of the arms of the fork, saidprojecting portions of the pin adapted to ride over the bevel of the shoulders and drop into the cradle, and a locking device swiveled on the pin between the arms and adapted to be turned up to form a spacer between the inside of the top wall of the female member and the pin so as to prevent the pin ends jumping out of the cradle. Y

6. In a coupling head, the combination of a female coupling head in the form of a bell, a pair of shoulders inside of the bell at each side provided with beveled front portions and a cradle at the rear of each, said bell being provided with a slot in the top, a male member having a forked end with a cross pin passing through the forks and project ing to the sides, alocking device swiveled on the pin between the arms of the forked end and comprising a sleeve, a cam, a radially projecting bolt and a sliding sleeve with a spring for tending to press the sleeve against the cam, the said locking device Vbeing arranged to be turned over into the slot to" allow the cam to form a spacer between the pin and the inside wall of the bell to avoid the pin ends jumping out of the cradle.

In testimony whereof, I sign this specifi-Y cation.
